So, level-up moves are only passed if they are learned while inside of the breeding center? And am I still doomed if I teach a TM to a female pokemon? x_x
By the way, I did some more testing:
- Female lvl 54 Venusaur from FR (Sludge Bomb, Frenzy Plant, Leech Seed, Sleep Powder) X Ditto: baby had only Tackle and Growl.
- the same Venusar as above, with Return instead of Frenzy Plant: baby still has Tackle and Growl.
- Male lvl 31 Relicanth from Emerald (Water Gun, Rock Tomb, Yawn, Take Down) X Ditto: baby had Tackle, Harden and Rock Tomb.
- the same Relicanth as above, with Earthquake instead of Water Gun: baby had Tackle, Harden, Rock Tomb and Earthquake.
Neither Venusaur or Relicanth gained a level, while there.
So... I suppose the babies will only have a level-up move after hatching if their parents learn it while in the Day-Care.
And Relicanth had Rock Tomb because it was a TM move, even though it learns it by level-up (level 15, according to Serebii).
Sorry if I'm mistaken at some point. x_x
